Problems solved by technology

When the fruit of Marigold officinalis is mature, the seed embryo in the seed is in the spherical embryo stage, and the seed does not germinate in the year of sowing, and it takes nearly two years to germinate and grow in a small amount, which greatly limits the development and utilization

Embodiment Construction

[0009] The quick after-ripening method of side marigold seeds, its steps are as follows:

[0010] 1 Materials and methods

[0011] 1.1 Experimental materials and processing

[0012] In spring (early May), the aggregated fruit balls of Marigold officinalis were collected, and after the aggregated fruit balls were dried and the seed coats were removed, they were treated with different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) After soaking in a mixed solution with 6-benzylaminopurine (6-BA) for 48 hours, mix the seeds with river sand (1:2) and put them into a wooden tank with good air permeability, cover with a plastic film and place them indoors for temperature change deal with.

[0013] 1.2 Morphological establishment, physiological post-ripening and sowing of marigold officinalis seed embryos

[0014] Seeds treated in 1.1, wherein the mass concentration of 2,4-D solution is controlled at 0.50-2.50 mg·L -1 , the mass concentration of 6-BA solution was contro...

Abstract

The invention relates to a seed breeding method, and particularly relates to a rapid adonis amurensis seed after-ripening method. The after-ripening method comprise the following steps of: drying adonis amurensis aggregate fruit balls, removing seed coats of the aggregate fruit balls, and immersing the aggregate fruit balls in a mixed solution of 2.50-3.00 mg / L 2,4-dichlorphenoxyacetic acid and 0.60-0.70 mg / L 6-benzylaminopurine for 48h; and uniformly mixing seeds with river sand, and carrying out temperature changing treatment on the mixture in a wooden tank indoors for 88-102 days, wherein the wooden tank has a good ventilation property and is covered with a plastic film, thus finally developing the seeds into mature cotyledon embryo seeds. The temperature changing amplitude and time of the temperature-changing treatment are that the daytime temperature is 20+ / -2 DEG C and the treatment lasts for 12h, and the night temperature is 10+ / -2 DEG C and the treatment lasts for 12h; and the mixing ratio of the seeds to the river sand is 1:3. Based on the treatment by the method, the adonis amurensis seeds develop from globular embryo into heart-shaped embryo and finally develop into the mature cotyledon embryo seeds. Low-temperature treatment breaks cotyledon embryo dormancy to achieve seed germination; and the method has a great significance to artificial large-scale plantation of high-quality adonis amurensis seedlings.

Description

[0001] technical field [0002] The invention relates to a seed cultivation method, that is, a rapid post-ripening method for marigold arborescens seeds. Background technique [0003] In the prior art, side calendula ( Adonis amurensis Regel et Radde) is a perennial herbaceous plant of the genus Calendula in the family Ranunculaceae. The height of the plant is 5-30cm, clustered, the flowers are solitary on the top of the stem, the flowers are bright yellow and shiny, the flowering period is from April to May, the aggregated achenes are spherical, and the fruiting period is from May to June. Lateral marigold flowers are early spring snow-topped plants that can be used for early spring landscaping. When the fruit of Marigold officinalis matures, the seed embryo in the seed is in the spherical embryo stage, and the seed does not germinate in the year of sowing, and it takes nearly two years to germinate and grow in a small amount, so the development and utilization are greatly...
